Genes affected

SLC17A3 (HGNC:10931): (solute carrier family 17 member 3) The protein encoded by this gene is a voltage-driven transporter that excretes intracellular urate and organic anions from the blood into renal tubule cells. Two transcript variants encoding different isoforms have been found for this gene. The longer isoform is a plasma membrane protein with transporter activity while the shorter isoform localizes to the endoplasmic reticulum. [provided by RefSeq, Aug 2012]

The c.1085C>G (p.A362G) alteration is located in exon 10 (coding exon 9) of the SLC17A3 gene. This alteration results from a C to G substitution at nucleotide position 1085, causing the alanine (A) at amino acid position 362 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
